flO ALL WH'OM IT MAY CONCERN: l v

Be it known that I,- JOHN H. CHAPMAN, of Utica, New York, have inventeda newand'useful Improvement in the Mode of Elevating Hay Eorks and thelike.

The nature of my 4i'nvention consists in the'use of'a turning post andcasting-olf pulleyin connection.with\r the rpes and pulleys in use insuch cases. Where theusual rope and pulleys are used, the draught is ina straight line from the lower' org'round pulley, and 'as barn-yards aresometimes small, or there may be something in the way, it becomesinconvenientat times to raise the load to the desired point.{And then,again, whenthe load has been raised -it is necessary to back up thehorse to allow the fork to'descend. l To obviate these objections I seta stout post in the-yard', at, say, abcuthalf the distance from thelower pulley the horse would ,have to travel if he drew up the load in astraight line as mentioned; and when elevating the load the horse isdriven 4around the post and turned in direction of the starting point,and when the load4 has reached the proper poi-nt the roperis' dischargedor cast olf from the'post and. the fork deseen-dsby its own gravity.When the load has been carried to the extreme point to which it is to beelevated, the horse is at thestarting point, having travel-led only thedistance to raise the load, and not twice the distance, as he would haveto travel inthe ordinary modes of elevating the fork; thatis, travellingin a direct line the distance -necessary to elcvatethe load, and when itis discharged returning to the starting, point.

Figure I is a perspective view of the' invention. Figure '2 is asectional view of the casting-oli' pulley; and Figure 3 is a planthereof. I i A A is the post; B is the guide; C is the ycap on the post;C C are stops therein; D is a studon whichl the pulley E turns; E E arenotches on the upper edge of the pulley E; F is the casting-off plate;Fl is a stop on the under side to catch in the notches E E; FZ-isaprojection on the underside of F to determine its motion between C 0';G is the draught-rope; and H is the ground pulley. I, l l

The post A may be set in the earth or in any other substantial manner.On the side on which Athe horse l advances is set '.theguide B, whichmay be set in the ground or attached to the post-in such manner a's thatwhen the draught-rope strikes it, it will slide up until it falls intothe groove ,on the pulley E. The post and guide may be of wood or metal.The cap C is of cast iron made to it on the top of the post A, withlthestud D cast thereon; anden this sturdvl) plays the pulley E, which'isalso of cast iron, having Ia series oi' notches, E/ E', onlits upperedge, say about one inch apart, with the square shoulders of each in thedirection of the horse as he faces the post invdriving toward it. On thesame stud Dis-the 'casting-oh' plate which' is alsol of. cast iron,-andis made to turn horizontally over the pulley E. 'lhe outer end of Fis.curved downward below the lower' side of the pulley E, and extendsbeyond the upper edge of the capC, vwhich outer end has also a skewon-its upper surface sloping from the direction of the barn-or groundpulley.4 On its under side is a stop, Fl, just over the notches E E',which catches into them' when the pulley is reversed, but which allowsthe notches to slide under it when the load is being elevated. .On theside of the cap are the stops C C', which, with the projection F2 on theunder side of the cast-oil` plate, regulate the distance suchlplate maytravel. v

The mode of operation-is as follows: The horse attached to the elevatingrope inthe usual way is driven toward the post A, and when he reachesitis turned around it; the rope then strikes the guide Band 'is carriedbyiitup to the pulley E, as the horse advances. When 'the load hasreached the-,desired point, the horse is stopped and the load dropped,and the horse being backed tive or six inches allows the pulley E toturn backward, `and the notches E E catching the stop Fl-carry back thesaid casting-oft` plate F, which from its form necessarily turns underthe rope and lconsequently, raises the rope up, and when it has turnedAback aboutonethird way round it has cast it oitl the pulley, If the loadis carried to the highest point, the horse at the time the rope is castolf will have returned to the starting point, and all'that isnecessary'is to turnhim about, when he is' ready to elevate anotherload.

The advantages of this invention are that it ischeap and simple, andallowsoi'- the moving of the horse in a-smaller space and saves one-halfof the travel. There are many other eontrivances by which the rope maybe cast off either by hand-or automatically, which Awill readily occurto any one. at once.

What I claim as my invention,l and desire to 'secure by Letters Patent,is-

1. In a hayl fork elevating apparatus or the like, the post A, incombinationwith. the draughtropeG and ground pulley H. i

2. The pulley E, and the casting-ott` plate F, constructedA andyoperating in combination substantially as described.
